To see if the compiler supports namespace-qualification, try:
--
#include <vector>
int main() {
std::vector<int> test;
return 0;
}
--
To see if the compiler supports specific "using", try:
--
#include <vector>
using std::vector;
int main() {
vector<int> test;
return 0;
}
--
To see if the compiler supports generic "using", try:
--
#include <vector>
using namespace std;
int main() {
vector<int> test;
return 0;
}
--
To see if the compiler *requires* namespaces, try:
--
#include <vector>
int main() {
typedef int vector;
std::vector<vector> test;
return 0;
}
--
A proper C++ compiler should be able to link and compile all of these. Only
C++ compilers that support C++ namespaces correctly should be able to compile
the last one.
Is that enough, or do you need more?
